EnergyBus〔http://www.energybus.org/〕 is an open standard for integration of and communication between electric components of light electric vehicles based on DC. It includes standards for both a communications and power distribution bus and a corresponding connector system. Data transmission is based on the CAN bus, specifically CANopen. EnergyBus is standardized through CAN in Automation in CiA-454.〔http://www.energybus.org/Further-Info/Downloads/CiA-454-Presentation〕 The EnergyBus specification is published through the EnergyBus Association, based in Germany. Members are individuals, as well as manufacturers of components, vehicles, systems, and retailers. Members are from all over the world, and include Bosch, Panasonic, Sanyo, Deutsche Bahn, Philips, and VARTA.〔(List of EnergyBus Members )〕 One major goal of the EnergyBus effort is compatibility of charging equipment with different battery types and chemistries for E-Bikes, pedelecs and other light electric vehicles (LEVs). == Layers == The EnergyBus standard is defined on several layers. The physical layer consists of the plug and socket used to connect separate components. The EnergyBus connector contains 6 contacts. Two contacts are for DC power up to 1.5 kW. Two wires carry auxiliary DC power to drive non-power components, such as energy management systems and sensors. Finally, two wires carry the CAN data bus high and low lines. Currently, EnergyBus power lines support DC voltages between 12 and 48 volts DC. The current is currently limited to 30 A, for a capacity of up to 1.5 kW. An extension up to 60 A is in the works, also 300 A is under draft. The Information Bus layer ensures components of the electric-, drive- and security-system of a vehicle or charging island system work properly together, even if they are put together without planning. The Information Bus definitions define messages and how they are exchanged for specific use cases. The attributes of each message, and values inside the message itself, are defined. All definitions are specified for more than 10 different types of components. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EnergyBus」の詳細全文を読む スポンサード リンク
